A concussion suffered a week ago appeared at first that it would prevent Welker from joining his Denver Broncos in their visit to Gillette Stadium, the place where Welker became a star before departing as a free agent. But Welker passed the NFL's concussion protocols on Friday and has been listed as probable on the Broncos' injury report, meaning he's likely to play on Sunday night. Welker participated in practice in full on Friday.

Cornerback Champ Bailey (foot) and tight end Julius Thomas (knee) both were listed as questionable for Sunday's game.

For New England, tight end Michael Hoomanawanui did not practice for a third straight day on Friday and will not play Sunday. Kyle Arrington (groin), Alfonzo Dennard (knee), Steve Gregory (finger), Aqib Talib (hip) and Leon Washington (ankle) all were listed as questionable. Danny Amendola (groin), Rob Gronkowski (back/forearm/hamstring) and Brandon Spikes (knee) were limited in practice Friday but are listed as probable for Sunday.
